In most cases updating your components, modules and plugins is an easy task.
First, you need to access your Joomla admin page and go to Extensions -> Manage -> Update.
Joomla will show you a list of all extensions that have a new version.
To update an extension to its latest version.
To do this, place a check next to the plugin name and press the Update button at the top left part of the page.
Check your website afterward to ensure that the update did not cause any glitches. If so, revert back to the previous update and contact the extension provider.
